FIRENIANS HELIVIET SPECIFICATION forming part of Letters Patent N 0.752,266, dated February 1K6, 1904,

Application filed December 6, 1902. Serial No. 134,096. (No model.)

To a/ZZ whom, t may concern,.-

Be vit known thatI, Cnozrnn T. THOMPSON, a citizen of the United Statesof America, residing at Cripplecreek, in the county or' Teller and Stateof Colorado, have invented certain new and useful Improvements inHelmets and Smoke-Excluders; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reierence being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecication. Y

My invention relates to a helmet and smokeexcluder for the use oftiremen and others who may have occasion to enter burning buildings orotherplaces where the smoke or noxious gases, or both, must be kept fromthe mouth and nostrils in order to make it possible for the person toremain and perform any eiiicient service.

The invention is provided with receptacles for chemicals, the saidreceptacles being in communication with the space inclosed by theldevice, whereby the impurities of the air resulting from breathing areneutralized or in some way changed, thus enabling the user to work for aconsiderable time or indeinitelyy when cut od froml a supply of pure oratmospheric air. The nature of thechemicals employed, except as aboveexplained, will not be set forth in this specification, as nothing iskclaimed thereon in this application.

Briefly stated, my improved device consists of a garment attached to anordinary hat or' helmet, the latter being of the type worn by firemen.Instead of this specific construction of hat or helmet, however, anyother suitable or desirable construction for covering the head may beemployed. The garment or jacket is attached to the hat or helmet so asto exclude the smoke, and it extends downwardly around the body of thewearer to the waist, or thereabout, where it is secured by means of abelt, tightly buckled to exclude the smoke from below. Springs areinterposed in front of the belt, being located in a pocket to permit a4limited degree of elasticity,lwhile holding the garment or jackettightly against the body of the wearer. Above the belt andinside of thegarment or between the latter and the body oi' the wearer are located anumber of receptacles adapted to hold some of the chemicals employed,suiicient space being left to allow a free communication between thereceptacles and the mouth and nostrils of the wearer. Another receptacleis exteriorly located and connected in front with the space inclosed bythe garment by a suitable tube or conduit, its object being to permitthe passage of a gas from the outer receptacle to the space within thegarment.

IHaving brieiiy outlined my improved device, as well as the function itis intended to perform, I will proceed to describe the same indetaiLreference being made to the accompanying drawings, in which isillustrated an embodiment thereof.

In the drawings, Figure l is an elevation showing my improved device inuse. Fig. 2 is a section taken through the garment. Fig. 3 is anenlarged detail view of the window located in front of the garment,through which section taken' through the garment where the Vsprings arelocated. Fig. 7 is a detail view,

partly in section, illustrating an electricillu- `minating device, shownon a larger scale than in Figs. 1 and 2.

The same reference characters indicate the same parts in all the views.

Let the numeral designate the hat or helmet, to the rim of which on theunder side is attached the upper edge of the garment 6, as shown at 7,by means of suitable fastening devices whereby a perfectly tight jointis made. This garment may be made of canvas rubberlined or any othersuitable or desirable material which is impervious to Water and smokeand not readily ignitible. It should also be of sutlicient stiifness tostand out well from the face and head of the wearer below the rim ofthehelmet, and therefore not readily collapsible. Below the rim of thehelmet and directly in front of the eyes of the wearer is located a sortof window or transparent device 8, which covers an opening in thegarment and is secured thereto in any suitable manner. This device isshown in detail in Fig. 3. It may be composed of isinglass or mica orother suitable transparent material. It is preferred that this materialshould have sufficient toughness so that it will not break easily. Itmust of course possess the property of transparency to a suiiicientdegree for the purpose. As shown in the drawings, this window isprovided'with wires 8, which protect the transparent material. The wires`are. attached to metal end pieces 8, which are attached to the garmentand form a sort of sash to hold the window 8 in place. y

The lower part of the garment or jacket is provided with loops 10,through which a belt 12 may be passed. To the inside of the garment infront is attached a piece of material 13, forming an inside chamberlorpocket, in which are located a number of coil-springs 14, causing thisportion of the garment to yield to pressure from within or without. Thisyielding portion of the garment is located in the Zone of the belt andengages the body `of the user in front where the belt buckles.

Between the belt and the window and located inside of the garment infront is a number of receptacles 15, open at the top and of theconstruction best shown in Fig. 5. Each of these receptacles is abox-like device having an upwardly-projecting flange 15, which isriveted or otherwise suitably secured to the garment in front.Projecting rearwardly from the body of the receptacle is a sort of wireor rod forming a brace 15, which is shaped to conform to the curvatureof the body of the wearer. This brace engages the body, as shown in Fig.2. Between the body portion of the device and the brace is an open spaceto permit the free circulation of air or gases within the inclosedchamber. To the upper back portion of the garment is attached areceptacle 16, from which leads a tube 17, whose extremity remote fromthe receptacle communicates with-the interior of the garment in front,as shown at 18. v This receptacle 16 is preferably made of heavycotton'web rubber-lined and air-tight, the material being of suicientstrength to withstand one hundred pounds pressure, or thereabout.

All of the joints of the device or the points of attachment of exteriorparts are so formed as to exclude the smoke and surrounding gases,

^ thus making the garment or the combined helmet and jacket perfectlyair-tight.

The receptacle 16 is detachable, having straps 16, provided with holesto permit the entrance of buttons 6, attached to the gar-l mentexteriorly. This receptacle is provided with a valved inlet 16c at thetop for the introduction of its contents. This inlet should be tightlyclosed after filling to prevent the escape of gasexcept by way of theconduit 17.

Attached exteriorly to the garment or jacket in front is an electriclamp 19, mounted on a storage battery 20, which supplies the current.This battery is attached to the garment by means of a buttoned strap 21.The lamp is surrounded by a reflecting-hood 22, open in front to permitthe escape of rays of light in front of the wearer.

The arms of the garment are tight at the wrist, being composed of somesuitable elastic material 6". (See Fig. 1.)

From the foregoing description the use and operation of my improveddevice will be readily understood. The jacket is slipped over the headof the wearer and drawn down until the helmet is in place on the head.The belt is then buckled around the waist sufficiently tight to excludesmoke and gases. Itis assumed that before the jacket is put on thechemicals to be employed in purifying the air have been placed in thevarious receptacles. The head and body/of the wearer as far as the waistare then enveloped and entirely protected by the air-tight jacket andhelmet, enabling the user to work with impunity in places where it wouldotherwise be impossible for him to remain on account of smoke and gases,or both.

Having thus described my invention, what -I claim is- 1. In an apparatusof the class described, the combination with a helmet, of asmokeexcluding jacket attached to the helmet and arranged to be fastenedaround the body of the wearer and provided with a receptacle on theinside, substantially as described.

2. The combination with a helmet, of a jacket whose upper extremity isattached to the helmet and whose lower extremity is provided with afastening-belt, and receptacles attached to the jacket between thehelmet and the belt and located on the inside of the garment for thepurpose set forth.
